Description

– M48Z512A:

= 4.75 to 5.5V, 4.5V ≤ V

– M48Z512AY:

= 4.5 to 5.5V, 4.2V ≤ V

– M48Z512AV:

= 3.0 to 3.6V, 2.8V ≤ V

≤ 4.75V

PFD

The M48Z512A/Y/V ZEROPOWER RAM is a

non-volatile, 4,194,304-bit Static RAM organized

as 524,288 words by 8 bits. The devices combine

an internal lithium battery, a CMOS SRAM and a

control circuit in a plastic, 32-pin DIP Module.

≤ 4.5V

≤ 3.0V

PFD

■ Battery internally isolated until power is applied

For Surface-Mount environments ST provides an

equivalent SMT solution consisting of a 28-pin,

330mil SOIC NVRAM Supervisor (M40Z300/W)

and a 32-pin, (Type II TSOP, 10 x 20mm) 4Mb

LPSRAM. Both 5V and 3V versions are available

(see Table 2 on page 7).

■ Pin and function compatible with JEDEC

standard 512K x 8 SRAMs

■ SOIC package provides direct connection for a

SNAPHAT top which contains the battery

■ SNAPHAT housing (battery) is replaceable

The unique design allows the SNAPHAT battery

■ Equivalent Surface-Mount (SMT) solution

package to be mounted on top of the SOIC

package after the completion of the surface-

mount process. Insertion of the SNAPHAT

housing after reflow prevents potential battery

damage due to the high temperatures required for

device surface-mounting. The SNAPHAT housing

is keyed to prevent reverse insertion.

requires a 28-pin M40Z300/W and a stand-

alone 128K x8 LPSRAM (SNAPHAT top to be

ordered separately

■ PMDIP32 is an ECOPACK package

The SNAPHAT battery package is shipped

separately in plastic anti-static tubes or in Tape &

Reel form. The part number is “M4Z32-BR00SH1.
